Carefully engineered with Beat Thermal Chokes made of highly conductive and efficient gold-treated coating for minimal-loss power delivery and integrated Dr.MOS MOSFET that both saves space and reduces operating temperatures. For the latest workstation motherboard, ASUS introduce the industry's most durable 12K solid capacitors, and exclusive ASUS ProCool power connectors. X99-E WS is built to stay cool under pressure — and boosts performance, power efficiency and product longevity into extreme levels!

ASUS is the world's first motherboard manufacturer to introduce 12K solid capacitors, and X99-E WS is of course equipped. These Japanese-made capacitors are the most durable in the industry, able to endure up to 12K hours at 105 °C and 1.2M hours at 65 °C. This is far higher than the temperatures generated by everyday computing, so X99-E WS is built for endurance . Our 12k capacitors also boast lowered equivalent series resistance (ESR) for increased efficiency and minimized heat generation — improving overall performance!

ProCool Power Connector

ProCool Power Connectors

ASUS ProCool is the power connector reinvented! Compared with traditional power connectors, ProCool connectors ensure an exceptionally close and secure connection with the X99-E WS motherboard. This design is much stronger, and it also benefits power efficiency: the flush connection enables lower impedance and better heat dissipation, allowing cooler operating temperature.

Beat Thermal Choke

Higher stability and lower power loss with Beat Thermal Choke

ASUS Beat Thermal Chokes deliver great durability and up to 93% power efficiency under normal operation. A special fin design results in 3-5℃ lower choke temps for added stability, which is increased exponentially by use of highly conductive and efficient gold-treated coating. This translates into minimal-loss power delivery.

Q-code logger is your one-touch status checker that lets users easily check system status at any time. Plug a flash drive into adjacent USB port, press the motherboard's dedicated Q-Code logger button and all ASUS Q-Code event logs for the current live session will be copied to the drive even with the system off.

ASUS Dr. Power hassle-free power supply health monitoring

As the X99-E WS is meant for professional users who rely on non-stop operation, stable power delivery is critical. Real time power supply health detection helps prevent sudden system shutdown and provides hassle-free notifications should power delivery be insufficient. Additionally, LED messages on the board clearly indicate any relevant power issues in the event your system fails to boot.

This is the first platform to support DDR4 memory, and it is capable of overclocking memory up to DDR4 3200+ MHz with all eight DIMMs fully loaded! ASUS-exclusive T-Topology circuit design plus patent-pending OC Socket unleash the full potential of DDR4 by minimizing crosstalk and signal reflections. Thanks to our expertise in motherboard layout design, signal timing issues are also greatly reduced, resulting in improved stability and overall performance. ASUS works with almost every DDR4 memory vendor to ensure the best compatibility – so you're assured reliable performance from your favorite brands.

All-round energy efficiency

EPU

With the Energy Processing Unit (EPU) you will enjoy from system-wide real-time power savings, controlled via a simple onboard switch or the AI Suite 3 utility. EPU detects and adjusts power consumption according to the PC's needs — automatically. It can also reduce CPU wattage to an indicated level or enjoy even more savings with Away Mode, which creates an extreme energy-saving scenario by shutting down unused extra I/O controllers and reduces the graphics cards' power level while you're away, so the PC consumes only the energy it needs — and not a drop more!

Advanced fan controls for ultimate cooling and quietness

Fan Xpert 3

Fan Xpert 3 puts 4-pin/3-pin CPU and case fan controls in one place. It scans each fan's characteristics and delivers custom settings for each fan based on the dedicated area temperatures detected by hardware thermal sensors. Make sure every fan achieves the best balance of cooling performance and low noise. Fan Xpert 3 supports hardware-level PWM/DC combo mode for both the CPU and case fans. It even can reduce the CPU fan speed to below the default minimum, for extra-quiet and power saving operation during light loads.

Faster, smoother gaming – always. Intel® Gigabit Ethernet has the serious double advantage of communicating directly with CPUs and offering high TCP and UDP throughput. This significantly reduces the processor's workload, so there's more power for your game and your gameplay.

Up to 2X-faster UDP game-data performance

ASUS engineers used IxChariot, an independent network-assessment test tool, to determine just how much quicker Intel Gigabit Ethernet deals with the smaller (sub-256 byte) UDP data packets that are vital for responsive gaming. The results are in — and with X99 your game-data packets flow up to two times (2X) faster than competing gaming-LAN technologies!

Multi-GPU support

With support for both NVIDIA® SLI and AMD CrossFireX 2/3-WAY configurations, the X99 motherboard enables multi-GPU setups so you can harness the full power of the latest graphics technologies to drive games at 4K and beyond.
